Dereah Sister Hypnosis App is a 3D adult touching simulator made with Unity by BouSoft. You play as a male protagonist interacting with a girl through real-time tactile scenes. The game gives broad freedom to touch many areas of her body, including the head, feet, sides, cheeks, breasts, buttocks, and belly, while emphasizing silky hair and soft textures. She can be placed in standing, sitting, crawling, or lying poses, and pose changes can be made smoothly. Players can use a movable camera or a fixed camera aimed at a selected body part. The presentation is animated 3DCG, and themes include mind control, teasing, and sex toys.
The current build is v2.1.2 + DLC, released on January 12, 2024, and it is an ongoing version rather than a finished release. It runs on Windows and supports Japanese, English, and Spanish. The patched build is uncensored. The version history records earlier fixes, including improved Y-shirt penetration, adjusted joint bending, sound fixes, shader changes, wipe-camera improvements, and bug corrections.
Developer's description
It's a 3D touching game with a strong degree of freedom and obsession. You can experience interactive touches in real time.
You can touch almost all parts of the girl's body, from her head to the soles of her feet, and even her sides and cheeks.
Her hair is silky smooth, and her soft parts such as her breasts, buttocks, belly, and cheeks are soft.
She can be made to stand, sit, crawl on all fours, or lie down. Posing can be changed seamlessly.
There is a camera that can be moved freely and a fixed camera that focuses on a specific part of the body.

MKUltra862024-08-11★★★★★
I enjoyed the storyline and having the option to interact with so many areas of her body. The gameplay was a little janky although having a proper mouse might make it smoother(I only have a mousepad) but I still found…
lolsassman20042024-02-29★★★★★
I'm a sucker for these games, exactly as advertised regarding the interactions, if you're a freak for doing whatever you want wherever you want and having the freedom to do so with a decent arousal mechanic, reactions and voice acting…
God of Debauchery2023-10-29★★★★★
This is for v1.2.2 Decent gameplay for a bit, but once you can finally have sex and the (actually decent) plot twist is revealed, it becomes disgustingly grindy with very minimal reward for the grind. Play for a decent fap…
